Claims. (CI. 20-55) My invention relates to windows and more particularly to means for securing storm sash and screens within the window casings of buildings.

Oneof the objects of my invention is to provide compensating means whereby storm-window and screen combination frames may be fitted and secured within dissimilar sizes of window casings thereby eliminating the necessity of stocking the wide range of sizes of combination frames usually carried by distributors in order to quickly meet various size demands in the field.

Another object of my invention is to provide compensating means or adapters for securing the combination frames to the casings in a tight and precisional manner and which means are selectable from a wide variety of stock sizes to accord with' the demands of, the particular installations thereby materiallyreducing the large number of stock sizes ordinarily provided in the combination frames.

A further object of my invention is to provide a combination frame capable of having attached thereto preselected adapters for attaching the frame to a window casing and in a manner to compensate for the discrepancy in sizes between the frame and the casing;

A still further object of my invention is to provide a combination frame which is so constructed and arranged whereby selected compensating means or adapters may be easilyattached thereto for securing a precisional and tight fit of the frame relative tothe, window casing.

An important objectof my invention is to provide a combination frame equipped with compensating means of the foregoing described character which is simplein construction, durable in use, efficieut in operation, economical in manufacture, and capable of installation without the services of highly skilled help.

With the above and other objects in view, as will hereinafter appeanthe invention consists in the combination and arrangement of parts hereinafter set forth and illustrated in the accompanying drawings from which the several features of the invention and the advantages attainedthereby will be readilyunderstood by thoseskilled in the art.

tion frame 5 which issecured within a window casing 6 2,960,734 Patented Nov. 22, 196 0 ice of a building B. The frame 5 is constructed of metal, for instance, extruded aluminum and includes side rails 7. The side rails 7 are provided with a ternary of tracks 8 in which are slidably mounted screen and storm sash as is customary in combination frames of this type. Each of the side rails 7 is fashioned with a laterally disposed and lengthwise extending flange 9 formed on its outer face with a plurality of spaced longitudinally extending ribs 10 defining therebetween similarly extending grooves 11. Inasmuch as the side rails 7 are extruded, precisional dimensioning of the ribs and grooves is not feasible where mass production is desired, it being understood that, in mass production of the frames, variation of size with respect to the ribs and grooves is an accepted factor.

In order to secure the side rails 7 to the blind stop 12 of the window casing 6, I provide each with an adapter strip or member 13 having an outer margin secured to the adjacent blind stop 12 by means of screws 14 as clearly illustrated in Figure 4. The opposite margin of'the strip 13 is provided with a yoke 15 having spacediun er and outer walls 16 and 17, respectively, for receiving therebetween the flange 9 and which outer wall 17, on its inner face, is formed with longitudinally extending ribs 18 defining grooves 19 therebetween for interfitting relation with the ribs 10 and grooves 11 of the flange 9, as disclosed in Figure 4. The thickness of each of the flanges 9. including the ribs 10, is slightly less than the opening between the inner wall 16 and the ribs 18 of the outer wall 17, as clearly discernible in Figure 5, thus enabling the flange 9 to be laterally received within the yoke 15 for securing the frame 5 to the casing 6.

Inasmuch as the distances between the rails and the casings may vary in different installations, the adapter strips or members 13 are suppliedin a multiplicity of widths whereby an appropriate width may be selected to compensate for the size differential of a frame and casing thus enabling a distributor or dealer to stock a small range of sizes of combination frames. In order that the members 13 may be secured in fixedand anchored relation with the flanges 9, they are of a somewhat resilient construction and transversely undulated throughout their length with the crests of the undulations defined by parallel planes spaced 9. distance slightly greater than the inner surfaces of the inner and outer walls 16 and 17 of the yokes 15. By flattening the members 13 throughout their length the walls 16 and 17 will be disposed in parallel planes thus permitting the yokes to receive therein the flanges 9, as illustrated in Figure 5, and effect interfitting of the ribs within the yokes upon release and return of the members 13 to their normal undulated condition as shown in Figure 6. Obviously, by again flattening the members 13in the foregoing disclosed manner, the members may be readily removed from the flanges, if desired.

From the foregoing it will be apparent that the adapter strips or members 13 provide an efficient and economical means for readily attaching combination frames to window casings and which permits the stocking of frames of fewer sizes merely by providing a materially greater number of adapter members in a wide range of widths. Furthermore, it will be apparent that my novel form of compensating means is so connected to the combination frames and the window casings of the buildings as to effect a tight and sealed fit therewith even though the outer faces of the blind stops or casings may be disposed in dissimilar planes. Moreover, it is to be distinctly understood that while I have used the term blind stop herein as defining mounting means, the term is to be interpreted as applying to any mounting surface to which it is essential or desirable for the compensating means; to be attached, a v

Without further elaboration, the foregoing will so fully explain the invention that others may, by applying current knowledge, readily adapt the same for use under various conditions of service. Moreover, it is not indispensable that all the features of the invention be used conjointly since they may be employed advantageously in various combinations and subcombinations.

It is obvious that the invention is not confined solely to the use herein disclosed in connection therewith as it may be utilized for any purpose to which it is adaptable. It is therefore to be understood that the invention is not limited to the specific construction as illustrated and described, as the same is only illustrative of the principles involved which are capable of extended application in various forms, and the invention comprehends all construction within the scope of the appended claims.

It will also be understood that while the frames may be fabricated in various stock sizes, the adapter members are provided in a materially greater number of sizes for selective connection to the frames as the occasions may warrant, the widths of the members varying greatly, for example, /2 to 1% as indicated in Figure 4- of the drawings.
